RFID Screw Tags(2025 new)

RFID Screw Tag is an intelligent label that embeds an RFID (Radio Frequency Identification) chip into the head or interior of a screw, combining fastening functionality with data storage/transmission capabilities. It interacts with a reader via wireless RF signals to enable unique identification, tracking, and management of objects, making it suitable for high-value equipment, industrial assets, or scenarios requiring concealed installation.

2. Working Principle

• RFID Technology: The chip and antenna inside the tag receive RF signals emitted by the reader and reflect back stored data (e.g., ID, production information).

• Frequency Types:

• Ultra-High Frequency (UHF, 860-960 MHz): Long-range (up to 0-10m), supports batch reading, but requires anti-metal design.

3. Product FeaturesPhysical Characteristics

• Material:

• Screw Body: Stainless steel, titanium alloy, etc., offering corrosion resistance and high strength.

• Tag Component: Epoxy resin/ceramic encapsulation, dustproof and waterproof (IP67/IP68).

• Size: Compatible with standard screw specifications (e.g., M3-M12), customizable length.

• Installation Method: Direct replacement for standard screws, no additional space required.

Electronic Performance

• Chip Types:

• Read-Only (e.g., UHF 860-960MHz, IMPINJ, NXP).

• Read-Write (e.g., HF 13.56MHz, NTAG213): Storage capacity up to 144 bytes, supports data modification.

• Anti-Interference Design: Metal isolation layer or magnetic materials to prevent signal attenuation in metal environments.

• Temperature Range: -40°C to +150°C (industrial grade).

4. Application Scenarios

• Industrial Asset Management: Track critical screws in machinery and pipeline valves to prevent loosening or theft.

• Automotive/Aerospace: Record screw torque and installation time to ensure compliance.

• Smart Buildings: Conceal marking of steel structures and curtain wall screws for easy maintenance.

• Anti-Counterfeiting & Traceability: Tamper-evident design for luxury packaging and high-end electronics.

5. Technical Parameters

6. Advantages & LimitationsAdvantages

• High Concealment: Appearance identical to standard screws, tamper-resistant.

• Durability: Resistant to vibration, acids/alkalis, lifespan up to 10 years.

• Efficient Management: Batch scanning improves inspection/inventory efficiency.

Limitations

• Higher Cost: More expensive than standard RFID tags, suitable for high-value applications.

• Metal Interference: Requires special design (e.g., ceramic antenna) to avoid signal shielding.

7. Selection Guide

• Environmental Needs: Choose stainless steel + IP68 for outdoors; ceramic encapsulation for high-temperature environments.

• Data Requirements: Opt for read-write chips if frequent data updates are needed.

• Compatibility: Ensure frequency alignment with existing RFID systems.
